Water drinking acutely raises blood pressure. The pressor effect of water is an important yet unrecognized factor in studies of blood pressure. Doubling water intake increases daytime blood pressure.
In some patients, water increases systolic blood pressure dangerously in the supine position. These patients should avoid water before retiring.
Effects of Adequate Hydration
